Question

If n open parentheses A close parentheses equals 4 comma blank n open parentheses B close parentheses equals 3 comma blank n open parentheses A cross times B cross times C close parentheses equals 240, then n left parenthesis C right parenthesis is equal to

  1. 288  
  2. 1  
  3. 12  
  4. 2  

The correct answer is: 2


    because blank n open parentheses A cross times B cross times C close parentheses equals n left parenthesis A right parenthesis cross times n left parenthesis B right parenthesis cross times n left parenthesis C right parenthesis
    therefore n open parentheses C close parentheses equals fraction numerator 24 over denominator 4 cross times 3 end fraction equals 2
